About & disclaimer
About this site
Carry-On Sizes is a free reference for anyone flying with a carry-on. On budget airlines especially, bags cost extra, and a bag that's slightly too big can cost more at the gate than the ticket. We collect each airline's published carry-on and under-seat bag limits in one place so you can check your bag before you fly.
Every figure is copied from the airline's own official page and shown with a link and the date we checked it. See Sources & method.
Not affiliated with any airline
This site is independent. It isn't affiliated with, endorsed by or sponsored by any airline. Airline names are used only to identify their published baggage rules.
Rules change
Airlines change bag sizes, weights, fees and fare bundles often, and rules can differ by route, aircraft, fare and booking date. Gate staff have the final say. This information may be out of date or incomplete and is not advice. Always confirm with your airline before you travel. We aren't responsible for fees or denied bags.
Links and advertising
The site currently has no ads, no sponsored content and no affiliate links. Some pages show clearly marked placeholder boxes (for example "Check price" buttons or flight, hotel and eSIM slots). These are inactive: they don't link anywhere, show no prices and load nothing from third parties. If we ever activate affiliate links, we'll label them and update this page and the privacy policy first.
